Spartan Carbon 27.5 Mountain Bike Frame

Dialed in on enduro tracks across the globe and ready to tackle your favorite singletrack comes DeVinci's Spartan Carbon 27.5 Mountain Bike Frame. Built to inspire confidence on burly terrain with its 6.5-inches of terrain-taming Split Pivot suspension and geometry honed from feedback of its team riders, this bike is ready to slay. The Spartan is consistently a leader in the 27.5-wheeled enduro category and this most recent generation evolves with a redesigned frame that increases stiffness and tire clearance, as well as refined geometry that improves stability when the trail points downward.

DeVinci gives this new Spartan a full carbon frame that helps improves stiffness and responsiveness for excellent handling and suspension performance. DeVinci takes frame stiffness a step further by making the transition to Super Boost 12 x 157mm rear spacing. Before you might balk at the thought of a new hub standard, 157mm hub spacing has been around on downhill bikes for a number of years. Super Boost simply widens the hub flange to improve the spoke bracing angle, resulting in a much stiffer wheel that's better able to resist lateral flex while cornering, braking, and charging through technical terrain. In addition to the stiffness benefits, Super Boost allows DeVinci to keep the chainstays super short while still clearing a 27.5 x 2.6-inch tire and up to a 38t front chainring, pretty impressive numbers that give you a wide range of rubber and gearing options.

DeVinci is well known for its use of a Split Pivot rear suspension. Designed by suspension guru Dave Weagle, Split Pivot is comprised of a main pivot and a concentric rear axle pivot separated by the chainstay (hence the name Split Pivot), as well as the brake link (seatstay) that floats between a rocker link and the concentric rear pivot. The floating brake link sets Split Pivot apart from other suspension designs by its ability to isolate braking forces from acceleration and suspension forces, resulting in unwavering traction across rough terrain, even while braking or pedaling. Many suspension designs firm up under braking, causing a loss of traction and reduced sensitivity. Split Pivot feels fully active throughout the travel and soaks up chunky rock gardens and square-edged hits with a smoothness unmatched by most suspension designs, all while maintaining a supportive platform for pedaling, climbing, and popping off trail features. Suspension performance is further improved by the switch to a Trunnion-mounted metric shock, as the Trunnion mount pivots on bearings rather than bushings, reducing overall friction for a more sensitive suspension response.

The Spartan also sees updated geometry that gives you an extra edge when the trail gets rowdy. Longer reach paired with a slacker head tube angle give the bike more stability on descents and high speed sections, providing some extra confidence to let go of the brakes when the trail gets steep and sketchy. With Super Boost rear spacing, DeVinci is able to keep the chainstays to a stubby 16.8-inches despite the massive tire clearance, giving the bike a playful feel that encourages jibbing and corners like it's on rails. The geometry is also adjustable via a flip-chip that's conveniently located at the shock's upper linkage, allowing you to switch from the default "low" position to a "high" position that raises the bottom bracket and steepens the head angle to improve pedaling performance on big days with lots of climbing.

DeVinci employs their mountain bike specific DMC-G carbon lay-up for the Spartan. Using EPS molding, DeVinci creates a monocoque carbon frame with flawless consistency throughout the carbon layers, eliminating resin-pooling and inconsistencies that can negatively affect the strength of the frame. DeVinci puts a lot of emphasis on frame strength and rigidity, and while some might argue that their frames are overbuilt, we appreciate the bombproof and stiff construction that inspires absolute confidence when you're smashing through technical terrain even if it means a little extra weight. It also allows DeVinci to offer a lifetime frame warranty to the original owner. The frame has internal cable routing for clean lines throughout and comes with molded frame guards for the downtube and chainstay to protect your investment from impacts while silencing chain slap. The frame has a bottle cage mount inside the main triangle, great for hot laps and silencing the forum comments.
